고속철도 궤도/토공노반 장기 측정 및 성능평가 = Long-term Measurement and Performance Evaluation of High-speed Railway Track/roadbed

다국어 초록 (Multilingual Abstract)

Recently, many concrete slab tracks have been adopted in high-speed railway. However, it is vulnerable to roadbed settlement compared to gravel tracks. Therefore, it was necessary to evaluate the long-term performance about roadbed and track of the concrete slab track. In this paper, the performance of track and roadbed is evaluated using long-term high-speed rail data. The measurement items are the Wheel load, Lateral load, Acceleration, Road pressure. The measurement period is from the beginning of construction to three years after opening. For the measurement method, a representative value of the measurement data was selected and compared with the reference value.
